*-currently doubtful about this, but here’s a long solution you might want to try to get Handoff on MBA 2011 and Mac mini 2011. Bluetooth Low Energy: Handoff requires that your devices are connected/paired over Bluetooth. And not just any version of it. Apple designed Handoff specifically to work over Bluetooth 4.0 (Low Energy). So, only those devices that support Bluetooth v4.0 will be able to handle Handoff. Interestingly, some users have said that using a Bluetooth 4.0 adapter made Handoff work on their incompatible Macs. But there are also users who have had no luck there.
